[PHP] count clicks to count most important news
I have a website that posts the most important news according to the number of clicks to that news the question is : what is the best way to prevent multiple clicks from the same visitor?

Not a fool-proof method, but use Javascript on the client-side to stop users' from continuous clicking. Then create a token and verify the click on the server-side before considering the click as being acceptable.

I'd recommend using POST data for this reason, as it's a lot more difficult for people to game. I agree, POST data is indeed the way to go here. Personally, I would use a like image-like thing which is actually a button, using some clever javascript (personally I would use jquery for this) you can then POST data to the server based on the click. Then set a cookie which disables the button (and keeps it disabled on future visits). This should prevent average person from repeatedly clicking it. You could also log the person's IP adress and filter based on that aswell; combining various methods would be best in this case I think. To prevent the method which Ashley mentioned, using POST data isn't enough. You would want to guarantee that the link came from YOUR server instead of some different place. There are multiple ways to do this: - use a unique key as an argument in the POST which can only be clicked once. Register the key in a database before serving the page, and then unregister it once it has been served and clicked. Though if a person were to repeatedly open the page, your cache would be exhausted, and the method would become useless. - require a referrer address to come from your domain; also reasonably easily circumvented in this case - there are more, but it really depends on how much effort you want to put into preventing attacks and how much effort you expect others to put into attacking it. For example, large sites like youtube are sure to use extensive measures to prevent people from spam-clicking in any way. While sites that only cater to say 3 visitors a month don't require all that effort in the first place.

I'm assuming this is not a voting system, and the news items you're counting are sourced from your own site and, with all due respect to Ash, unlikely to be a target for false clicks. All you're really wanting to do is prevent the site from registering multiple hits from the same user in a short period of time. I would probably use memcached on the server-side to store short-term information about clicks. When a news item is loaded... 1) Construct the memcache key: newsclick_article_id_ip_address. 2) Fetch the key from memcache. 3a) If it does not exist, log the hit. 3b) If it does exist, compare time() with the value and only log the hit if time() is greater. 4) Store the key with a value of time() + 300 and an expiry of the same value. This will prevent hits being logged for the same news item from the same IP address within 5 minutes of other hits. Other alternatives would be to use cookies (could get messy, and not very reliable since it requires the response from click 1 to be processed before click 2 gets started), Javascript (as suggested by tedd but without the token - it would work pretty well and would be a lot easier to implement than the above, but you sacrifice having full control over it). If I'm interpreting the requirement correctly my solution is almost certainly overkill, and a simple Javascript solution would be more than sufficient. -Stuart -- Stuart Dallas 3ft9 Ltd http://3ft9.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Count the Number of Certain Elements in An Array
Hi, This seems like a pretty simple problem, but I can't seem to be able to figure it out. I have a lot of elements in an array, and some of them are duplicates, but I don't want to delete them because I have other purposes for it. Is it possible for me to find out the number of certain elements in an array? For example, // Create a simple array. $array = array(1, 2, 3, 4, 5, 3,3,4,2); $total = count($array); echo $total; If I run the code, the value of $total would be 9. However, what I really want to do is to get the values of the different instances of each, like: 1 = 1 2 = 2 3 = 3 4= 2 5= 1 Is there a simple code that I use to find this out? Thanks for your help.

[PHP] count() total records for pagination with limit
I seem to recall that it is possible to count all instances of a query
that is limited by $RecordsPerPage without repeating the same query. I
believe that COUNT() had to called immediately after the SELECT word but
I neglected to bookmark the source. Dummy!
I don't like the idea of count(*) over count() or something like that as
it seems rather slow fram what I read.
right now I do this:
$sql = SELECT * FROM book
WHERE id IN (SELECT bookID
FROM book_author WHERE authID IN (SELECT author.id
FROM author WHERE LEFT(last_name, 1 ) = '$Auth')) ;
$Count1 = mysql_num_rows(mysql_query($sql, $db));
$books = array();
$SQL = SELECT * FROM book
WHERE id IN (SELECT bookID
FROM book_author WHERE authID IN (SELECT author.id
FROM author WHERE LEFT(last_name, 1 ) = '$Auth'))
ORDER BY $sort $dir
LIMIT $offset, $records_per_page ;
if ( ( $results = mysql_query($SQL, $db) ) !== false ) {
while ( $row = mysql_fetch_assoc($results) ) {
$books[$row['id']] = $row;
}
}
$Count = mysql_num_rows($results);
$Count gives me the actual rows for display - $Count1 gives me the total
rows available.
Can this be streamlined any?

Secondly, that won't do what the OP asked for. array_count_values returns an array which tells you how often each VALUE was found in that array. so: array_count_values(array(1,2,3,4,5)) will return: array(1=1,2=1,3=1,4=1,5=1). While what the OP wanted was: some_function(array(1,2,3,4,5)) to return 5 (as in the amount of values, not how often each value was found in the array). count() would do it directly, and the other suggestions people gave do it indirectly, assuming that the values between '|' are never 1 char wide. I think you'll find Kyle was suggesting that the OP use that function to count the |'s in the string. Add 1 to that and you have the number of elements explode will produce. More efficient if you're simply exploding it to count the elements, but count would be better if you need to explode them too. -Stut For the case where you want to explode a string and afterwards count the number of elements you wind up with, Maciek is right: count() is the correct function to use. array_count_values() will not work on the original string and after exploding will have no useful effect on the resulting string as far as counting the number of separators goes. If you don't actually need to explode the string but just want to count the separators, you could use some weird logic to get array_count_values() to count the number of times '|' appeared in the original string--but it would be pointless. count_chars() would be a much better choice for what you are suggesting.

Secondly, that won't do what the OP asked for. array_count_values returns an array which tells you how often each VALUE was found in that array. so: array_count_values(array(1,2,3,4,5)) will return: array(1=1,2=1,3=1,4=1,5=1). While what the OP wanted was: some_function(array(1,2,3,4,5)) to return 5 (as in the amount of values, not how often each value was found in the array). count() would do it directly, and the other suggestions people gave do it indirectly, assuming that the values between '|' are never 1 char wide. I think you'll find Kyle was suggesting that the OP use that function to count the |'s in the string. Add 1 to that and you have the number of elements explode will produce. More efficient if you're simply exploding it to count the elements, but count would be better if you need to explode them too. -Stut -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Count
I am wanting to create an select menu for displaying the order of the item on a page. I am guessing that I need to get the count of how many items are in the db and them put them into a select menu. Your question doesn't really make a great deal of sense. Your SQL could be: SELECT COUNT(*) FROM your_table WHERE 1 Which will give you a single numeric value back (the number of rows).

Re: [PHP] Count
Richard, Thank you so much for your response. The select would be created from the number of records in the db. option value=²$variable²$variable2/option The problem that I am having is rather than getting just the number of records, which is 3 currently, I would like it to be 1 for the first option, 2 for the second..., so that the user has the choice of any record. The idea would be to order the content by the highest number. I hope this makes more sense. -- Steve M. on 1/17/08 1:54 PM Richard Heyes ([EMAIL PROTECTED]) wrote: I am wanting to create an select menu for displaying the order of the item on a page.

[PHP] count vs mysql_num_rows
I've got a little function that just checks to see if something is in a mysql db. There are several ways to do this and was curious as to the best way.

Is this a joke? You are using a LIMIT 1, so your count is always going to be 1.
But, if you didn't use the LIMIT 1 and really wanted to see how many the results would be found,
then I would do it like this.
$SQL = SELECT count(id)
FROMiAdmin_users
WHERE name = '{$name}';
$results = mysql_query($SQL) OR die('Mysql Error: '.mysql_error());
$count = 0;
if ( $results ) {
list($count) = mysql_fetch_row($results);
}
return $count;

That explains the count() result. It seems to me that the first case

$doc-loadHTML($file);
$p = $doc-getElementsByTagName('p');
How would then wrap the following around each p tag:
form name=form target=_parent
action=/index.php?action=edit_paragraphfile='.$_GET['file'].'
method=post
input type=hidden name=old_html
value='.htmlentities($matches[0]).'
pa href=javascript:;

/form

anything within a p tag!

Only problem is that you could have a slight timing issue where the
select above gets done, then somebody adds a new image, and then you
display your counts, and then you display the list, and that extra image
is in the list, but not counted.
You *COULD* solve this by wrapping a transaction around the whole mess if
it's really critical, but you probably don't need it.

Re: [PHP] Count totals (might be 0T)
Hey, Thanks for replying.

Or by grabbing the data you want in the initial query and adding it all up BEFORE you start to do you display logic. So the second option would be: 1. Get all the data. 2. Loop through all the data creating the tally(s) you want. 3. Loop through the data again creating your visual gropings and throwing in the tally(s) you created earlier. Try both options and time them. Chris. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] count with match probelm
Hi,

$q=mysql_query(select cno,date_and_time,MATCH(ad_sub, ad_text)
AGAINST('$words') AS score from .$tcname.ads WHERE MATCH(ad_sub, ad_text)
AGAINST('$words') AND is_confirmed=1 LIMIT $limit1, $limit2);
which is running fine...my problem is I am using a class for pagination
which requires the total number of records that will be returned to break
the query into pagesand which will give me the values of $limit1 and ,
$limit2 which i will use in the above statement...but running a count() is
not working, it gives me an error, what other options do i have other than
running the same query twice and using mysql_num_rows? (which i think would
be quite intensive/wasteful as i am querying @ 100 rows each time)
This is my count() query, maybe theres a problem here?
$how_many = mysql_result(mysql_query(SELECT COUNT(*), MATCH(ad_sub,
ad_text) AGAINST('$words') AS score from .$tcname.ads WHERE MATCH(ad_sub,

This is pretty much a MySQL question, really...
But: There is a new-ish SQL_CALC_FOUND_ROWS constant you can use in your
query to get MySQL to tell you how many rows you would have gotten without
the LIMIT clause. You may be able to use that.

[PHP] count index prevents ldap_add() after ldap_search() directly
I'm doing a bunch of LDAP work with PHP-4.3.6 and keep running up
against this annoyance. If I do an ldap_search() and get the first
entry, I can't then tweak some of the attribute/values and then
directly use ldap_add() to put a new version into the directory. The
reason is that the ldap_get_entries() function returns any array or
sub-array with a gratuitous count index.
For example, the following code (error checking removed for clarity):
$results = ldap_search($ldapConn, $baseDN, uid=cshenton);
$entries = ldap_get_entries($ldapConn, $results);
$entry = $entries[0];
echo entry=pre . print_r($entry, true) . /pre;
Prints the following (with some tedious attribute/value pairs removed):
entry=
Array
(
[cn] = Array
(
[count] = 1
[0] = Chris Shenton-2
)
[0] = cn
[sn] = Array
(
[count] = 1
[0] = Shenton
)
[1] = sn
[objectclass] = Array
(
[count] = 2
[0] = inetOrgPerson
[1] = qmailUser
)
...
[count] = 14
[dn] = cn=Chris Shenton-2,ou=Headquarters,o=National Aeronautics and Space
Administration,c=us
)
My code then fiddles with the old DN to create a new entry, then tries
to add it to LDAP:
if (! ldap_add($ldapConn, $newDN, $entry)) {
die(ldap_add failed, errno=. ldap_errno($ldapConn) . :
. ldap_error($ldapConn));
}
It fails (but oddly, ldap_error() reports Success). The problem is
the 'count' and attribute-named indices (e.g., 'sn') in addition to
the numeric indices:
Warning: ldap_add(): Value array must have consecutive indices 0, 1, ... in
/home/cshenton/public_html/newhorseadmin/ldap_search_add_test.php on line 45
ldap_add failed, errno=0: Success
Am I missing something or is it not possible to simply take a search
result, then add it back? Seems I have to strip out all these
gratuitous 'count' and non-numeric indices each time, which isn't
intuitive, obvious, or the most direct way of doing things.
Thanks.

query result?

Re: [PHP] COUNT(*)
Actually that does retrieve the number of rows..
// Query
$query = SELECT COUNT(*) AS count FROM pet;
// Execute Query
$result = mysql_query($query);
// Get the result of query named count
$count = mysql_result($result,0);
echo $count. is the number of rows;
Cheers!

Subject: [PHP] COUNT(*)
Hi
I used to use old fashioned mysql quieries but moderm mysql
apparently became more flexible so. I want to understand how to use
some of the new features like COUNT(*)
Let's say I have
$result=SELECT COUNT(*) FROM pet;
$sql=mysql_query($result);
while ($row=mysql_fetch_array($sql)){
$pet_name=$row['pet_name'];
echo ..;
}
the question is how do I actually retrieve the number of rows of sql
query result?

[PHP] Count on Multiple Tables
I've been stuck on this one all morning. Can't seem to figure it out. I have 2 tables, one with affiliate sales and another with affiliate clickthroughs. I have to query both tables, so that I can get clickthrough dates, hits, and then query affiliate sales table to get number of orders for each date. I want to display the results like this: DATE | TOTAL HITS | TOTAL SALES 05/03/2003 6 1 05/04/2003 7 0 I've managed to get dates and total hits by using the following query: SELECT DATE_FORMAT(affiliate_clientdate, '%M %D, %Y') AS date, COUNT(*) AS hits FROM affiliate_clickthroughs WHERE affiliate_id = '111' AND affiliate_stores_id = '123' AND MONTH(affiliate_clientdate) = '06' AND YEAR(affiliate_clientdate) = '2003' GROUP BY date; But then I can't get the total number of sales on affiliate sales table. Any suggestions? Your help is greatly appreciated. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hey, who are you callin' names?!?

% I need to evaluate a number if greater than 7 and add a value per increment.
Greater than seven is easy. Adding a value is easy. Per increment can
be a little tricky but we'll assume for the moment that the window is 1.
The code
$sum = 67 ; # starting value
$trg = 7 ;# trigger value
$add = 6 ;# what we add each time
$num = 10 ; # what we're evaluating (hardcoded here!)
for ( $num ; $trg $num ; $trg++ )
{ $sum += $add ; }
print when num = $num, sum = $sum\n ;
should do for a starting point, though, and produces
bash-2.05a$ php -q /tmp/inc.php
when num = 10, sum = 85
bash-2.05a$ php -q /tmp/inc.php
when num = 20, sum = 145
bash-2.05a$ php -q /tmp/inc.php
when num = 7, sum = 67
bash-2.05a$ php -q /tmp/inc.php
when num = 1, sum = 67
when run.
Extra credit if you write it as a recursive function :-)

Re: [PHP] count up from 7
Huh?
Not really following what you want to achieve, but:
?
$n = 9;
$floor = 7;
if($n $floor)
{
$diff = $n - $floor; //eg 2
// no idea what you want to do from here
}

Try the following code, please note you may want to trim() the string as

$char = 'hello world';
$number_characters = strlen(str_replace(' ', '', $char'));

Re: [PHP] count characters without space
who knowes how to count the charcaters in a string without the space character? Using a regular expression to strip out all the spaces before passing to the word counting function seems easiest. You'll be left to adapt it to PHP, but the regexp is: 's/ //g' That removes all spaces. If it gives an error, try s/\ //g to escape the space. Pass the result to whatever you use to count the number of characters. -Jeff SIG: HUP -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] count errors
I have a function that resets the count of fields with certain values when
called. 99.9 percent of the time it works fine. However occaisionally it
wont update the database. Even after breaking the selects up it still fails
sometimes. If anyone has an idea of why I would really appreciate hearing
it. The code is below.
Thanks,
